high idle
hi all,
Ive got an '89 f150, recently it has had an intermittently high idle. I was checking today for vacuum leaks and couldnt find any, so whilst running I disconnected the IAC valve, that made the idle drop back to about 600rpm, although the iac is fairly new could this mean that it is the iac valve that is faulty?
